Results and Analysis. We report results using the same evaluation metrics as in [1]}; Table REF  and Table REF  shows evaluations at the segment and event levels, respectively. Audio, Visual and AV refers separately to audio, visual, and audio-visual events. As the name suggests, segment-level F-scores are evaluated at the level of segments, while the event-level F-scores are computed by concatenating positive consecutive snippets in the same event categories and then computing an event-level F-score based on mIoU = 0.5 as the threshold. We also compute two aggregated metrics, Type@AV (Macro F1) and Event@AV (Micro F1) which are averaged audio, visual, and audio-visual event evaluation results and the F-scores considering all events for each sample, respectively.
